Modeling Early Earth Climate with GEEBITTpart of Cutting Edge:Topics:Early Earth:Activities This activity requires students to use a simple spreadsheet model to consider the roles of solar luminosity, planetary albedo, and greenhouse gases in controlling surface temperature in the present and during the ...

How Do We Estimate Magma Viscosity?part of Pedagogy in Action:Library:Teaching with SSAC:Examples SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

Bubbles in Magmaspart of Pedagogy in Action:Library:Teaching with SSAC:Examples SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

What is the Volume of a Debris Flow?part of Pedagogy in Action:Library:Teaching with SSAC:Examples SSAC Physical Volcanology module. Students build a spreadsheet to estimate the volume of volcanic deposits using map, thickness and high-water mark data from the 2005 Panabaj debris flow (Guatemala).

Porosity and Permeability of Magmaspart of Pedagogy in Action:Library:Teaching with SSAC:Examples SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

Flood Frequency Analysispart of Cutting Edge:Courses:Environmental Geology:Activities This assignment asks students to do a flood frequency analysis to determine the size and stage of various floods and determine if the town of Crawford, OH is likely to be flooded or not. Outcomes: learn to work ...
